SASH-PULLEY.

QSPECIPICATION forming part of Letters Patent No. 315,347, dated April 7, 1885.

Application filed January 9, 1885. (No model.)

To all whom it may concern.- 'y

Be it known that I, JOHN B. ScHRoDER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sash-Pulleys, of which the following is a speciiication.

The object of my invention is to cheaply con-A struct a sash-pulley having a non-wearing ro journal-bearing. Sash-pulleys when in use are not easily accessible for the purpose of lubricating them, and it is found that after a short use they begin to Work hard, make a disagreeable noise when the sashes are raised or lowered, and the bearings are soon cut7 and the pulleys destroyed. To overcome these objections, I core out aspace Within the pulley in casting it, and then insert the journal, and mold Babbitt metal around the journal within the recess formed by the core.

\ In the accompanying drawings, Figure l is a side elevation of my pulley. Fig. 2 is a radial section of the saine, taken through line x x of Fig. l. Fig. 3 is a central section taken through line y y of Fig. 2.

The pulley A is cast of any suitable metal. The center of the pulley is cored out to receive the polished journal B and the Babbitt metal bearing C. (Shown in stipled section in Figs. 2 and 3.) From the annular depression in one side ot' the pulley a hole, a., is bored, to meet the hollow space in the center of the pulley. The pulley shown has a flat groove around the periphery to receive the weight- `chain or a flat metal band. When a cord is to be used, these grooves will be of course semicircular in cross-section.

After the pulley is cast itA is placed Hat upon its side with the hole a uppermost.

The journal B, which snugly fits the openings in the walls of the central` 4o" non-Wearing bearing is vthus secured at no j greater cost than the common pulley now generally used.

It is not intended herein to broadly claim the nouwearing or anti-friction journal-bea`ring; nor does the invention relateto any particular material for the non-wearing bearing,

but is limited to the peculiar chamber, as shown, and adapted to receive any well-known anti-friction bearing, which may be molded within said chamber and around the axle.

What I claim, and desire to secure by Letf ters Patent, is

The pulley A, having Within it the Central chamber and opening, a, and the non-Wearing bearing C, molded within said chamber and around the journal B, substantially as shown and described. 4 i
